Chiefly, the metal wire-feed and laser additive manufacturing (AM) is a deposition process to produce larger mechanical parts required for aerospace, shipbuilding, automobile, and mold repair industries. The principal advantage of metal wire-feed AM is the high deposition rate compared to an assisted metal powder-feed AM, and metal powder-based fusion AM. During the wire-feed deposition process, the feed orientation is a critical parameter managed at all stages of processing. A better surface finish is attained when the melted wire flows smoothly through the process, and a wire feed direction that is utilized opposite to the deposition direction yields the best results. To improve the surface quality of metal 3D printing, we designed a rotating wire feeder, the feed direction of which varies with the direction of deposition; all free-form lines which thus exhibit identical surface qualities. Here, we use a rotating stage to orient the wire-feed direction according to the bead direction, a slip ring to supply electrical power to the feeder motor, and utilized two rotating channels on a plate to supply Ar gas and extract fumes safely during the processing stage. We evaluated the rotating wire feeder by building various parts as needed to the equipment.
